To (tZZ whom, it ntay concern.-

Be it known that I, JOHN GUIRY, a citizen of the United States, and aresident of New York city, in the county of New York and State of NewYork, have invented certain new and useful Improvements inDumping-Scows, of which the following is a specification.

The invention relates to improvements in dumping-scows; and it consistsin the novel features and combinations of parts hereinafter described,and particularly pointed out in the claims.

The scow of my invention comprises two suitably separated pontoonsconnected together by a deck, a longitudinal series of bins or hoppersarranged upon the scow and disposed between the Vertical planes of thefacing sides of said pontoons, a horizontally and longitudinally slidinggate for the bottoms of said bins or hoppers, and means for operatingsaid gate, said bins or hoppers at their front and rear inner lowerportions having inclined or converging walls and said gate having aseries of openings adapted at the proper time to register with the lowerends of said bins or hoppers, so as to permit the discharge of therefuse downwardly between said pontoons. The aforesaid sliding gate willwhen in one position close the lower ends of the bins or hoppers,so thatthe latter may be filled, and when moved from such position said gatewill carry its discharge-openings below said bins or hoppers, and atsuch time the refuse may at once escape downwardly.

The object of my invention is to produce a very durable andeasily-operated scow and one lacking the disadvantages and complexity ofscows at present in use having hinged doors at the bottom of therefuse-receptacles.

The invention will be fully understood from V the detailed descriptionhereinafter presented,

transverse section of same on dotted line 3 3 of Fig. 2; and Fig. 4 is adetached top view, partly broken away, of same with the bins or hoppersremoved, Fig. 4 being presented to illustrate more clearly theconstruction of the sliding gate.

In the drawings, 10 and 11 designate the two pontoons, which areconnected at their forward ends by a deck 12 and at their rear ends by adeck 14, while at their middle portions the said pontoons are connectedtogether by transverse beams 15, upon which aresupported the.

longitudinal grooved rails 16 for the series of ball-bearings 17. (Shownmore clearly in Figs. 3 and 4:.)

Upon the ball-bearings 17 is placed the sliding gate 18, containing aseries of equidistant openings 19 and solid portions 20. The gate 18 inthe employment of the scow is given a longitudinal sliding motion uponthe ball-bearings 17 by means presently to be described. The solidportions 20 of the gate 18 are connected in series by longitudinal bars21, Fig.

4, which are disposed over the rails 16 and prevent refuse passingthrough the openings 19 from accumulating upon the rails 16.

Above the sliding gate 18 and over the the longitudinal series of binsor hoppers 22,

formed by the sides 23 23 and partitions 24:, the bins 22 being equallyspaced and inde-' pendent of one another and each at its lower innerfront and rear portions having the inclines 25 26, converging downwardlyand leaving an opening in the lower end of the bin corresponding in sizeto one of the open ings 19 in the gate 18. The series of bins 22 are setdownwardly into the space between the upper portions of the pontoons 10and 11 and are supported upon said pontoons by means of shoulders 27,Fig. 3, formed on the sides 23 and engaging the upper inner edges ofsaid pontoons. The lower edges of the series of bins 22 are in closerelation to the upper surface of the gate 18, but do not bear upon saidgate, the latter being thus left free to be moved longitudinally belowthe bins 22 and upon the ball-bearings 17 The inclines 25 26 direct therefuse downwardly through the open lower ends. of the bins 22 when thegate 18 is in such position that its width of the solid portions 20 ofsaid gate 18. When the gate 18 has its solid portions 20" below the binsor hoppers 22, the latter may be filled with refuse, and the openings19-of space between the pontoons 1O 11 is mounted said gate will beconcealed and closed by the adjacent inclines 26 25, and when the gate18 has been moved longitudinally toward the rear the openings 19 willappear below the open lower ends of the bins 22 and the solid portions20 of said gate will pass below the adjac'ent inclines 26 25, and thusbe prevented from obstructing the outflow of the refuse from said bins.

Upon the forward and rear decks 12 14 are mounted in suitable bearingsthe transverse shafts 28 29, upon which are secured the winding-drums 3O31, to which are respectively connected chains 32 33, which chains arealso respectively connected to the front and rear ends of the gat 18 andare utilized for imparting to said gate its longitudinal slidingmovement, the drums 30 paying out the chains 32 when the drums 31 arewinding up the chains 33 and the drums 31 paying out the chains 33 whenthe drums 30 are winding up the chains 32. The shafts 28 29 and drums 3031 have simultaneous rotation imparted to them by means of thesprocket-chain 34 and sprocket-wheels 35 through the medium of thepinion-wheels 36, short shafts 37, and gear-wheels 38, said gear-wheels38 being fixed 'upon the shafts 28 29 and in constant mesh with thepinion-wheels 36, which are rigid upon the short shafts 37 carrying thesprocket-wheels 35. The sprocket-chain 34 may be set in motion by anyconvenient means or power, and in the present instance I illustrate acrank 39, applied to the shaft of the rear sprocket-wheel 35 forrotating said wheel in either direction and causing the movement of thesprocket-chain 34 in either direction in accordance, with the directionof movement it is desired to impart to the gate 18.

In Fig. 1 I illustrate the gate 18 as having been moved rearwardly so asto carry its openings 19 below the lower ends of thebins or hoppers 22for the purpose of permitting the discharge of the refuse through saidopenings. When it is desired to close the lower ends of-the bins 22, thecrank 39 will be operated to drive the upper reach of the chain 34forwardly, and at such time the shaft 28 having .been set in motion thedrums 30 will wind upon themselves the chains 32 and draw the gate 18forwardly to the position in which said gate is illustrated in Fig. 2,the solid portions 20 of said gate then closing the lower ends of thebins 22 and the said openings 19 being below the adjacent inclines 2625. When during the'rotation of the forward shaft 28 the gate 18 ispulled forwardly, the drums 31 will pay out the chains 33 in the sameproportion that the chains 32 are wound upon the drums 30. After thebins 22 have been filled and the scow has reached the place at which therefuse is to be discharged a reverse motion will be imparted to thesprocket-chain 34, its upper reach being then caused to travelrearwardly, with the result of causing the discharge from the bins orhoppers 22 will commence as soon as the gate 18 is set in motion in arearwardly direction, and a further advantage of the constructionpresented by me is that the bins may discharge their contents in shallowwater, if necessary, there being no hinged doors to be swung outwardlybelow said bins. It is my purpose that the sliding gate 18 shall beabove the water-line, and hence in the operation of the gate the latterdoes not reach the water and a space is provided above the water-linefor the discharge of the refuse. If, however, the load placed into thebins 22 should be such that the gate 18 should pass below thewater-line, it may be operated with entire convenience; but my purposeis to have said gate clear of the water. There are many well-recognizeddisadvantages in the employment of dumpingscows having hinged doors'atthe bottoms of the refuse-receptacles, and these disadvan tages areentirely obviated by my invention.

Below the front incline 25 of the forward bin 22 is provided a stop 40,against which the forward end of the gate 18 may abut when said gate isin its forward position, (shown in Fig. 2,) this stop assuring thearrest of the openings 19 below the adjacent inclines 26 25.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. A scow comprising the connected pontoons, and the longitudinal seriesof bins thereon adapted to discharge between said pontoons, combinedwith the longitudinally-arranged.

sliding gate 18 having solid portions 20 and containing the openings 19,longitudinal rails for supporting said gate upon said pontoonsand belowsaid bins, and means for movingsaid gatelongitudinally, the said solidportions 20 forming the bottoms for said bins when said gate is in oneposition and said openings 19 passing below said bins when said gate ismoved to its other position to carry said solid portions from below saidbins; substantially as and for the purposes set forth.

2. A scow comprising the connected pon-- toons, and the series of binsthereon adapted to discharge between said pontoons, said bins having"the converging inclines at their lower inner front and rear portions,combined with the sliding gate below said bins having openings adaptedto be moved into register with the lower ends of said bins, and meansfor sliding said gate, the said inclines being adapted to close saidopenings when the solid portions of said gate are in position to closethe lower ends of said bins; substantially as set forth.

3. A scow comprising the connected pontoons, and the longitudinal seriesof equallyspaced bins thereon adapted to discharge between saidpontoons, said bins having discharge-openings at their lower ends, andsaid openings being equally spaced, combined with thelongitudinally-sliding gate below said bins having openings adapted toregister with the said discharge-openings and also, when the gate ismoved to close the lower ends of the bins, to register with the spacesbetween said discharge-openings, and means for sliding said gate;substantially as set forth.

4. A scow comprising the connected pontoons, and the series of binsthereon adapted to discharge between said pontoons, combined with thesliding gate adapted to form bottoms for said bins and having openingsadapted, when the gate is moved for that purpose, to register with thelower ends of said bins, shafts at the ends of the scow and havingwindingdrums thereon, chains connected with said drums and said gate,and means for simultaneously rotating said shafts and drums and movingsaid gate; substantially as set forth.

5. A scow comprising the connected pontoons, and the series of binsthereon adapted to discharge between said pontoons, combined with thesliding gate adapted to form bottoms for said bins and having openingsadapted, when the gate is moved for that purpose, to register with thelower ends of said bins, shafts at the ends of the scow and havingwindingdrums thereon, chains connected with said drums and said gate,sprocket-wheels connected to said shafts, and the sprocket-chainconnecting said wheels for imparting simultaneous movement to saidshafts and drums and moving said gate; substantially as set forth.
